Professor Spangler

Hi, my name is Professor Spangler and I am going to teach you all about mean, median and mode. When given a set of numbers, it is quite simple to calculate these values, as well as the minimum and maximum values. The first step in finding these values is to organize your numbers in numerical order. The minimum value will be your first, lowest number in the list. The maximum will the be last, highest, number of the list. The mode is also very easy, it is the number that appears the most often. So whichever number on the list appears most frequently is your mode. The median is the middle value of all the numbers. You can start by crossing a number off the low end, then high, then low, then high and so forth until you are left with the middle value. If there are an even amount of numbers you need to add the two remaining numbers and divide by two to get your mean. If you have an odd amount of values, then your mean is simply the middle number. The mean is the most difficult to calculate but is still very simple. The steps to finding this value are to add all of your values together, and divide by the amount of numbers that are on your list. If you have a list of 8 numbers, you would add those 8 numbers together, and then divide by 8. The mean, median and mode are very important in mathematics, and now you know how to calculate then very quickly.

  1. I think you did a great job of explaining this in a straightforward way! Maybe some pictures would have been helpful, but its quite a simple topic so I can understand why you didn't include any. Well done!

  3. hi, lexi,

    you lesson topic is good, however, it could have used an actual worked example showing how to calculate mean, median, and mode. it was fun having you in class. good luck to you. =]
